Description | OsABI5 is a bZIP transcription factor, it's expressed in the panicle, specifically in mature pollen, of Oryza sativa L. Expression of the OsABI5 was induced by ABA and high salinity, and down-regulated by drought and cold in seedlings. The OsABI5 protein was localized in the nucleus, its N-terminus is necessary for trans-activation activity. It binds to a G-box element of ABRE and trans-activate reporter gene expression. Complementation analysis showed the expression of OsABI5 could rescue ABA-insensitity of abi5-1 during seed germination and result in hypersensitivity to ABA. Over-expression of OsABI5 conferred high sensitivity to salt stress, repression of OsABI5 promoted stress tolerance and resulted in low fertility by affecting pollen maturation. OsABI5 is a homolog of Arabidopsis AtABI5 (At2g36270). |
